Topographic base map Sample Clauses

Topographic base map. Develop a topographic survey map (1’ contour) of the project area that includes relevant surface features including buildings, property lines, water quality treatment basin sites, drainage channels, curbs, sidewalks, traffic signals, signal induction loops, signs, edge of pavement, power poles, drainage improvements, utility vaults, utility boxes, existing overhead and underground utilities (drainage, sewer, water, telephone, power, cable, natural gas, utility poles, guy wires, fire hydrants, valve boxes, hand-hole boxes, and vaults), fences, walls, and spot elevations, street cross-sections at 25-foot stations with grade shots at grade breaks and vertical offsets extending a minimum of five feet beyond the public right-of-way. Cross-streets will include cross-sections on a minimum of 25-foot intervals for a distance of at least 100 feet beyond the Pioneer Trail right-of-way and extend a minimum of five feet into private property.

Topographic base map. We propose to construct a topographic base map that starts with the initial existing topographic mapping discussed above and supplemented with more detailed field surveying in areas where there will likely be proposed prescriptions under the alternatives developed. Features to be captured in the survey will include but not be limited to buildings, property lines, water quality treatment basin sites, drainage channels, curbs, sidewalks, traffic signals, signs, edge of pavement, power poles, drainage improvements, vault boxes and all other infrastructure items listed in the RFP. We also anticipate conducting additional ground survey to define the slopes of culverts and to define the downslope grade line. Task 2 Assumptions:
